It does seem to work in the shower, as was advertised at the time. Good thing, since that's mostly what I got it for (I have a countertop model but this being right there in the shower makes it a little easier on hard days). I was able to do my whole mouth on one tank. The flosser does seem to have a timer but I just turn it back on if I have to.It really is pretty compact, will be nice for travel. I really like that you have a place to put the in-use tip away. Comes with a nice enough little bag. I don't know if I'd want to take it in my purse to work (as they seem to show) but you certainly could, in a larger bag.Not bad to hold at all, very occasionally I would have angle issues but you just need to adjust the tip relative to the water tank stem. You get used to it and then it's second nature. For one or two tight spots on my front teeth I have to tip my head some so it doesn't go past horizontal. Again, it becomes habit and you don't even think about it. Not a big deal at all. Do look at the pictures with a human (or the video) for a proper idea of this thing's size.The only real drawback I personally had was there were some little black flecks on it at the start. I remember being like 'should I wash the tips?' when I first opened it, and I was relieved to see they came in one of those sterile baggies. But then I noticed a fleck, and it was inside. I don't think the flecks were anything gross (they just felt like little very flat pieces of plastic) but I was still a little bit taken aback. I just rinsed the whole flosser out (it had a few much smaller ones in the nozzle storage compartment) and let any new tip run for a bit on high before I use it. Seems fine from doing that, no more problems.One thing that I will point out is this water flosser is like any other. It comes with different settings, and works amazingly for getting those hard to reach spots in your mouth. I love how compact it can be, and that there is a capability of storing it somewhere, since it is easily downsized. The cup you attach to the bottom could be used for both the water pick itself, and for rinsing after brushing your teeth.The best part - this even works after having had popcorn. As most know, popcorn is IMPOSSIBLE to fully remove from your teeth, so having something capable of removing it is wonderful.I am so glad I got this, and if it ever breaks, I will one hundred percent be getting another.Initial impression of this flosser is that looks to be a a very nice unit.It's very compact for travel as the entire unit fits inside the water reservoir.It also comes with a nice carry pouch.One thing that would have made this product perfect would be to provide a small plastic case for the water pick tips to be stored while travelling. They come in a plastic wrap to be torn and discarded.Including the charge block and cable is nice.Overall it seems like a well designed and made product.I will update the review once I have more experience with using the product.The full size of this water flosser is not small. It has a relatively large water tank for a travelling water flosser. It has a nice design that has a partition for storing the heads. The main body can be put into the water tank so It will be very small and handy to bring along. The power is good and the water stream is strong enough for general cleaning. I am bringing this for travel all the time.This traveling water flosser holds more water than any I’ve tried before. The four settings can be changed with a separate button from the power button unlike some others. The nozzle can be stored in a back compartment, and the water chamber holds the entire contraption when it collapses, not folds. All settings are pretty gentle compared to waterpik brand. I recommend it highly.I'm not sure why they say this is "foldable." It is compact. but it does not fold. It comes apart into two pieces, and the water well becomes a cover for the unit.This works great. It is easy to put together, with a little tube that pulls out of the bottom, and a little door at the back for hanging your pic. It has a neat little waterproof bag to store it all. There are 3 modes: pulse, low and high. I suggest you start on low, especially if you are not accustomed to water flossers. High is too much power for your gums at first.The water well is large enough for a generous flossing. There are specialty pics. I used the regular one, but my husband has a bridge and found the periodontal style can get to food that gets stuck between the gum and the bridge. He got out food that the regular dental floss would not dislodge.It takes a bit of getting used to handling this portable flosser. It is awkward to hold. The diameter is at least twice that of an electric toothbrush. Also, while it is portable, it isn't that small. It definitely takes up less countertop real estate than a full sized flosser, but it is larger than I expected it to be.Bottom line: It works great. If you have limited space and are looking for a good flosser, this would do fine.We've tried quite a few of these, since my son has braces. Some are better than others, and some are total junk.This one seems decent. It's still a bit awkward to maneuver, but not as much as some of the larger rectangular shaped ones are. The setting for the pressure seems to work decently, and has a low enough one for beginners that others often lack.I like that it has USB C charging, kudos to them for that, nothing worse in 2022 than companies still using old style USB plugs for the charging ports.Another nice touch that most seem to lack is the little storage bag for everything. I really appreciate that in health care items like this with various smaller parts.We really like this flosser because it's not too awkward and bulky. It's easy to charge and has an updated usb-c charger. We haven't traveled with it yet, but the compact design looks like it will travel well. It even has it's own pouch. Overall it's a great gadget sure to help with oral hygiene.
